Wavefront measurements of imaging systems by comparing a point-diffraction interferometer and a Shack-Hartmann wavefront sensorp
(2018-06-30)
Article.
Accés obert
Article.
Accés obert
In this work, we present a comparative study between two notorious techniques for wavefront characterization: Shack-Hartmann wavefront sensor and the Point-Diffraction Interferometer. The main goal of this work is to ...
Quantifying the synchronization of the spikes emitted by coupled lasers
(Institute of Physics (IOP), 2023-07-01)
Article.
Accés obert
Article.
Accés obert
Synchronization phenomena is ubiquitous in nature, and in spite of having been studied for decades, it still attracts a lot of attention as is still challenging to detect and quantify, directly from the analysis of noisy ...
Vegetation canopy height retrieval using L1 and L5 airborne GNSS-R
(Institute of Electrical and Electronics Engineers (IEEE), 2021-11-29)
Article.
Accés obert
Article.
Accés obert
Vegetation canopy height (CH) is one of the important remote-sensing parameters related to forests’ structure, and it can be related to the biomass and the carbon stock. Global navigation satellite system-reflectometry ...
Cloud-based single-frequency Snapshot RTK positioning
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-05-26)
Article.
Accés obert
Article.
Accés obert
With great potential for being applied to Internet of Things (IoT) applications, the concept of cloud-based Snapshot Real Time Kinematics (SRTK) was proposed and its feasibility under zero-baseline configuration was confirmed ...
Dynamics of a semiconductor laser with feedback and modulation: experiments and model comparison
(Optical Society of American (OSA), 2022-03-14)
Article.
Accés obert
Article.
Accés obert
We study experimentally and numerically the dynamics of a semiconductor laser near threshold, subject to optical feedback and sinusoidal current modulation. The laser operates in the low frequency fluctuation (LFF) regime ...

Article.
Accés restringit per política de l'editorial
We present an experimental study of the effect of continuous-wave optical injection (OI) from a vertical-cavity surface-emitting laser (VCSEL) on the timing jitter of a gain-switched discrete-mode semiconductor laser (DML). ...
Phase and baseline calibration for microwave interferometric radiometers sing beacons
(Institute of Electrical and Electronics Engineers (IEEE), 2020-08-01)
Article.
Accés obert
Article.
Accés obert
The relative phase and amplitude calibration between individual receiving elements are one of the key challenges in interferometric microwave radiometry. For monolithic interferometers, for example the Microwave Imaging ...
Nonlinear analysis of interconnected power converters: a case study
(2015-09-01)
Article.
Accés obert
Article.
Accés obert
In this paper the nonlinear dynamics of interconnected power converters in an islanded direct current (DC) microgrid is analyzed. By using a simplified scheme based on two cascaded converters we analyze the dynamical ...
Experimental evidence of swell signatures in airborne L5/E5a GNSS-reflectometry
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-05-29)
Article.
Accés obert
Article.
Accés obert
As compared to GPS L1C/A signals, L5/E5a Global Navigation Satellite System-Reflectometry (GNSS-R) improves the spatial resolution due to the narrower auto-correlation function. Furthermore, the larger transmitted power ...
